active partition or volume

The partition or volume from which the computer starts up. On a basic disk, the active partition must be a primary partition. For a dynamic disk, a dynamic volume cannot be marked active directly. However, a basic disk with a system partition can be upgraded to dynamic. After the disk is upgraded and the computer is restarted, the system partition becomes a system volume, which retains its active status.

Upgrading a basic disk with a system partition to a dynamic disk preserves the partition table information, which is required when reinstalling the Windows operating system.
